Polyhedron geometry definition
WebJul 2, 2024 · Polyhedron. In geometry, a polyhedron (plural polyhedra or polyhedrons) is a three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices. The word polyhedron comes from the Classical Greek πολύεδρον, as poly- (stem of πολύς, ) + -hedron (form of ἕδρα, or ). ‘many’; ‘base’; ‘seat’; Web1. In general, (the interior of) a polyhedron is defined as a connected subset of R n, bounded by a finite number of hyperplanes. It decomposes the space into two regions. If none of the bounding hyperplanes crosses the interior, we then have a convex polyhedron, which can thus be expressed as the intersection of a finite number of half-spaces ...
